Be' it known-that I, HARVEY D. Vl/oon, a citizen` of the Unitedv States, residing at Fayetteville, in the 'county-of Washington and State of Arkansas, `have invented cerf tainlmprovementsin Stoves, 'of which'the following is a specification,l

My "invention is a hygienic stove provid7A ing improvedfineans for' effecting' cornbus-y tion, with air'drawn taining the stove, andgfor heating fresh air` drawn ,frolnan .outside source, 'before delivering it to the" room to. replace the airL withdrawn. A i The characteristic construction and"func-r tions ofy my vinvention will morevfully ap` pear byareference to the `following description and the accompanying drawingsin illustration thereof. i In the drawings, Figure l Ais apartly sectional frontl elevation of a stove embodying, my'improvem'ents, and Fig. `2 is a partly same. My improvementain the 'form shown in the drawings, are embodied ina wood'st'ove terior shells l and 2c'om`bined withfthegfront-f and back plates 3 and 4, forming' the oval" heating chamber 5, the-shelll 2`contain`ing the inner back `plate .6, combining therewith and with theeplate 3 to form -theovalcombustion chamber 7fwithinthe heating chiunber. l' i The shellsl and 2 are preferably sheet metal, and theplatesrS and'll castings', pro vided with. flanges 8 and9 for-engaging the ends ol the respective shells andthe flanges 10 for supporting aA baille plate 11 above the chamber 5 which has lateral outlets 12 beneath the baille, the partsibeingconnected by the tie rods 13. rlhe back plate 6 is pro-4 vided with the oval flangel'by which it is secured within the shell 2, adjacent to the plate 4f, andthese plates are strengthenedv by their respective transversely extending' having the concentric, oval exterior and ineguribs 15 and 16.? 'The casting 3, forming the A is provided with the cenfront of the-stove, p trally placedfuel charging door 17 adapted to4 swing on the hinges 18, and with the ash door 19 adapted to swing on thejhinges 20 beneath the 'door 17. A pipe 21,]1Lined to the shell 1 midway between the feet 22 'and 23 on the ends 3 and 4, provides a fresh'air duct communicating with the bottom of the chamber. 5. Duets 24, controlled by registers 25, carry air from the room containing combustion chamber `ituel inthe lower part thestove and discharge the same through the openings 24'at the stoves ends into the lower part of the` combustion chamber 7 so that such airis distributed therein. A pipe 26, having a baffle 27 at its inlet, discharges the smoke from the side ofthe combustion chamber. The baille 27 is aplate held in the -ways 28 in which it slides and from which `1t can be removed. from the room' con- In the operation of the stove, whicliris delivered by discharged through the `the air, the ducts 24- and openings 24 to the 7,y Hows through the y .of such chamber, thence upwardly toward the top of the u chamber and thence downwardly to the discharge pipe 26, being swirled by; the oval .Wall 2 and efiiciently distributed'fso as to ellectinrproved combustion.` The air discharged through the duct 21 in tothe bottom of the. chamber 5 is heated asvit rises there through, whence ffreshheated air is discharged to the room through the ports l2 at the top of the stove. A

The characteristic construction, Ecompr'ising the'two shells of oval cross sections havingtheir` major axesr vertical, in combination With'thecastings or plates for closing their ends andftheducts for handling the air, is ,'mple, inexpensive,accessible, readily repaired, eilici'ent and hygienic.

Having described my invention, I'claim: l. A stove comprising an ovalshell form- Aing a ,combustion chamber, a concentric 'oval shell forming a* heating chamber around said'combustion chamber, a discharge pipe vwithwhichl said combustion chamber communicates'throlligh a curved side thereof, twyers on oppositesides of said discharge pipe and delivering air to saidcombustion chamber through said curved side and below the inletto said discharge pipe, a baille controlling said inlet to said discharge pipe so as to prevent the admissionof air ,at the bottom' thereof, whereby air admitted to said combustion chamber is swirled before being Idischargedl through said1dischargeV pipe, and means for passing air between said shells. Y 4 2. A stove of the character described, comprising spaced inner and outer shells curved in vertical cross-section, providing therebetween an air heating chamber having a lower air inlet and an upper air outlet, the

lnner shell 'forming a combustion chamber;

'an outlet conduit for products of combuslos tion passing through Lne corresponding curved side walls of the shells at a point spaced substantial' distances from the top and bottom-thereof und leading froml the 1 combustion chamber withont communicit-` ing. with the ail'v heating chamber; downwardly discharging air supply ducts zu'-A ranged between the inner andouter shells and communicating with theflower portion of the combustion chamber upon -the sume side thereof with the outlet conduit; and an J.
